STEAM FEED COOKER AND EVAPORATQR.

SPECIFICATION forming part of Letters Patent No. 537,647, dated April16, 1895.

7 Application filed January 2, 1895. Serial No. 533 534- (No model.)

To wZZ whom it may concern:

Be it known that I, WILLIAM RIPPLEY, of the city of Grafton, Jerseycounty, State of Illinois, have invented certain new and usefulImprovements in a Steam Feed Cooker and Evaporator, of which thefollowing is a full,

ing broken away to more clearly illustrate the.

same.

Referring by numerals to the accompanying drawing, 1 indicates the legsor standards of my improved cooker, there being four in number and thesame framed together near their lower ends by cross-bars 2. Longitudinalbars 3 are fixed to the upper ends of the standards 1, the ends 4 ofwhich are formed into handles. These bars 3 extend a slight distancebeyond one pair of the uprights 1 and have rigidly fixed between them bymeans of brackets 5 a vertical boiler 6, the same being of the doublewall pattern, thereby forming a water space 7.

Located beneath the boiler in the usual manner is a grate 8, accessbeing bad thereto through a hinged door '9. By means of a hinged door inthe upper end of the boiler 6, the proper fuel may be supplied to theinterior of said boiler and upon the grate 8. A pipe or smoke stack 11extends from the top of the boiler in the usual manner.

12 indicates a reservoir that is mounted upon the frame Work, the upperend of said reservoir being in a plane above the upper end of the boiler6. A horizontally arranged pipe 13 extends through the wall of thereservoir 12 at a point slightly below the center thereof and is joinedby an elbow 14: to a vertical pipe nected by an ordinary elbow 19 to ahorizontal pipe 20 that communicates with the lower end of the waterspace 7. A vertical pipe 21 is vertically arranged between andcommunicates from the separating chamber 16 to the horizontally arrangedpipe 20, said vertical 'pipe being provided with a cut-off valve 22.

A vertically arranged pipe 23 extends from a point near the lower end ofthe reservoir 12 to a point above the top of said reservoir, where it isprovided with a funnel 24:.

A cut-0E valve 25 is fixed in the pipe 23 above the reservoir 12 andadjacent the f unnel 24. The reservoir is fitted with a faucet 25 at acentral point relative its, height, and also with. an ordinary gageglass 26 and safety valve 27, said safety-valve being in the top of saidreservoir.

Extending vertically upward from the top of the reservoir 12 is a pipe28, upon the upper end of which is fixed a T-coupling 29. One end of aflexible tube, such as a hose 30 is adapted to be positioned in one endof the T-coupling 29, the lower end of said flexible tube being adaptedto discharge at any point desired, orin a suitable receptacle 31 inwhich the food to be steamed and cooked is placed. The other end of theT-coupling 29 is adapted to receive one end of a flexible tube (notshown), but when a single tube leads from said T-coupling, a plug 32 isinserted in one end of said T-coupling.

The operation is as follows: To fill the reservoir 12 the operator opensthe Valve 25 in the vertical pipe 23 which necessarily allows the waterdischarged into the funnel 29 to pass to the interior of the reservoir12. From said reservoir 12 the water passes through the pipes 18 and 20into the water space 7 of the boiler 6. It is essential that asufficient quantity of water be discharged through the pipe 23 to fillthe water space 7 of the boiler 6 and partially fill the reservoir 12. Afire being started upon the grate 8 within the lower end of the boiler 6necessarily heats the water within the water space 7 of said boiler andsaid heated water rising will create a circulation through the pipe 17,separating chamber 16,pipes 21 and 20 back to the water space 7 of theboiler 6. While generating steam the valve 22 must be open. Thus withina very short space of time, the entire volume of water in the waterspace becomes heated and steam generated. As the steam generates itpasses from the separating chamber 16 through the pipes 13 and. 15 intothe top of the reservoir 12, from thence through the pipe 28, T-coupling29, flexible pipe or hose 30 by which it is discharged wherever desired,or into a suitable receptacle such as 31.

Should it be desired to generate steam, and heat the entire volume ofwater, the valve 22 is opened,and as the water in the water space 7 ofthe boiler 6 becomes heated, a circulation will be established from thereservoir 12 through the pipes 18 and 20 into the water space 7 of theboiler 6, from thence through the horizontal pipe 17 into the separatingchamber 16, and from thence through the horizontal pipe 13 and verticalpipe 15 to the interior of the reservoir 12. Thus the entire volume ofwater becomes heated and the steam generated therefrom passes from saidreservoir through the pipe 28, T-coupling 29 and flexible pipe 30, ashereinbefore described.

Should the steam pressure within the upper end of the reservoir 12become too great, the safety-valve 27 will act in the usual manner. Bymeans of the glass-gage 26 the height of the water within the reservoircan at any time be readily ascertained.

It is essential that the Water line within the reservoir 12 never beallowed to get below the pipe 13. The faucet is for the purpose ofdrawing a small supply of hot water that may be desired.

A steam cooker of this construction will generate steam in a very shortspace of time, is extremely simple in operation, and is es peciallyapplicable for generating small quan= titles of steam withoutunnecessary time, labor and expense.

What I claim is 1. In a steam cooker, the combination of a steam boiler6, a water reservoir 12 located in a plane approximately with that ofthe top of the boiler, tubular connections 13, and 14 and 1 6 from thereservoir to the boiler, an inlet tube 17 discharging into the lower endof the reservoir, an outlet tube discharging from the upper end of thereservoir, and a T-coupling located upon the tube extending from theupper end of the reservoir.

2. A steam cooker, comprising a suitable framework, a boiler mountedupon said frame work, a reservoir located in a plane approximately withthat of the top of the boiler, tubular connections from the top of thewater space of the boiler to the interior of the reservoir, tubularconnections from the bottom of the Water space of the boiler to thebottom of the reservoir, a separating chamber interposed in the tubularconnection from the top of the water space to the reservoir, and tubularconnections from the separating chamber to the tube that leads from thelower end of the water space to the lower end of the reservoir.

In testimony whereof I affix my signature in presence of two witnesses.
